Aluminum should be ok, but you need thicker aluminum as its not as great of a conductor. Also, it will pit if its anywhere around saline air.Travis,
What about aluminum? I was wondering about using a light coat of silicon grease before attaching the bus bars as is done with marine batteries. I live in a high humidity area and have a few cells in storage in the house and they are already starting to show some signs of rust inside the threads.
Hi; limited experience in this but as already mentioned, Aluminium has only appr. 62% the conductivity of copper. Had a defect develop in a 175 transmig welder supposedly manufactured in NZ but in reality Asia, a connector strap made of aluminium only lasted 6mths, replaced it with a flattened 1/2" copper water pipe ; still going. Cost savings now can be expensive later. CheersTravis,
I don't have any pics to send yet as the rust is very light and only on the threads ( on some new unused cells). It just won't show up in the pics. I guess what I want to know is when using aluminum busbars should I assemble dry or is there a light lube which I can apply to the ends of the cells that will not act as an insulator when I bolt the busbars on? One of my friends suggested copper anti seize. Thanks
